Ok, here is the photo. Very dusty engine as we live on a short dusty road.
Road and PV problem now solved. Purge Valve is in center of pix. (Black with cable going to it.)
One of the problems we had in finding the source of Tat, Tat was the sound was "telegraphed" throughout the engine. IMO just wrapping the out side of the PV will not solve the problem. It needs to be removed/replaced , bracket bent out, and more padding installed.
Insist your dealer fix it right. We have not heard a sound from ours since Mark made the fix. A2Jack
